One of biggest mysteries in biology: how did complex eukaryotic cells evolve from simple microbes? ~1.8 billion years ago, an archaeal cell likely merged with a bacterium to form the first eukaryotic cell, but can we ever find direct evidence of this transformative event? 🦠 🚶‍♂️

Isolated in just 3 years! (previously, 12 years). We obtained two strains from 'Hodarchaeales', proposed to be closest to our archaeal ancestor. Our analysis suggests the ancestor was an anaerobic, syntrophic, peptidotrophic, archaeon with a simple intracellular structure and possible aerotolerance.
